   - Choose materials that can withstand the slurry's abrasiveness and corrosiveness. Common materials include high-chrome alloys, stainless steel, and rubber linings.

In firefighting systems, propeller pumps also play a crucial role. They provide the necessary pressure and volume of water needed to combat fires effectively. Their capability to move large quantities of water quickly makes them a reliable choice for fire departments, particularly in high-risk areas where rapid response is critical.

Wear Factors: Impellers are subject to high levels of wear due to the abrasive nature of slurries.Materials: Common materials for impellers include high-chrome alloys, natural rubber, and polyurethane.

   - Most slurry pump manufacturers provide selection charts that correlate slurry characteristics and operating conditions with suitable pump models.

   - Consider the type of seal (e.g., mechanical seals, packing) based on the slurry's properties and operating conditions.
